PIVOT FOR ABTICULATED CARS Filed A ug. 9, 1928 2 Sheets-Sheet 2 Patented Oct. 22, 1929 UNITED STATES PATENT OFFICE WALTER S. ADAMS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE J. G. BRILL COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYL- VANIA PIVOT FOR ARTICULATED CARS Application filed August 9, 1928.

This invention relates to articulated railroad cars, and is concerned particularly with a new and improved manner of pivoting of the articulation.

An object of my invention is to obtain a substantially universal joint at the articulation.

Another object is to devise means whereby the head of the king bolt will be raised slightly when the car goes over a hump in the rail.

Other objects will appear hereinafter.

In the drawings, which illustrate one form of my invention:

Fig. 1 is an elevation showing the invention in position at an articulation, the cars and truck being shown in broken lines;

F ig. 2 is a top plan of the articulated joint;

Fig. 3 is a vertical section therethrough;

Fig. 4: is a top plan of the socket-receiving member;

Fig. 5 is perspective view of a socket; while Fig. 6 is a perspective of a socket-receiving unit.

Referring more particularly to Figs. 2 and 3, the center sills 1 and 2 of the car units of the articulated structure each may have secured substantially at the extremities of their adjacent ends a socket member 3, comprising a base portion 4 and a halt-round lug 5, although this lug may have any desired form. These socket members 3 are secured to their respective sills by means of bolts 41*. The sills 1 may also be provided at their adjacent ends with out-turned flanges 6, 6 for a purpose which will be developed later.

These socket members each rest in a segmental socket-receiving unit 7, as shown in Fig. 6. This unit is preferably provided with a depression 8 into which the lug 5 snugly fits.

The units 7 in the present modification are formed from segments of about 150, and since two units are employed at each joint, some play is permitted therebetween. The amount of play in any given instance is determined by the size of the angle of the segment. The units 7 may be cut away as at 9,

Serial No. 298,527.

in order to snugly fit around the king bolt 10.

The units 7 may rest in a plate-shaped memher which may be provided with a flanged retaining rim 12, and which in the present instance is provided with a bearing surface 13 on its floor on which the units 7 play.

On its lower face the plate 11 may be provided with an annular flange 14, which re tains in position a spacing and guiding member 15 for the king bolt 10.

Bearing against the lower end of the member 15 is a spring 16 acting against a locknut 17, holding the king bolt in firm but resilient contact with the sills 1 and 2.

The plate member 11 is firmly fixed in the truck structure.

A tapped hole 18 is peferably provided in the head 19 of the king bolt, thus providing poeans for lifting the king bolt should it be ast.

As will be seenfrom the disclosure, the arrangement is such that when the car goes around a curve, the segmental units 7 will permit the cars to adjust themselves to it; and the lugs 5 will compensate for any break in the grade between the cars, as when the one car passes around the crest of a hill, etc. When the car goes over a hump on the track, the spring 16 will permit a slight movement of the king bolt.

Numerous modifications will be readily apparent to those skilled in the art to which this invention appertains, and it is intended that the scope of the invention be limited only by the appended claims.

I claim:

1. In a joint for an articulated car, sills on each car section, adjacent ends of said sills each terminating in a segmental socket member, a member fixed in the car truck under the joint, for securing said socket members, and a king bolt held by said lastmentioned member and retaining the sills in position.

2. A joint for an articulation in a car structure, comprising sills on the car sections, lug portions secured to adjacent ends of said sills, a plate-like member secured to the truck beneath the joint, said member receiving a king bolt, segmental members positioned for limsitioned for limited movementin the plate member, for receiving and acting as bearings for the lugs, the lags permitting up and-dewn movements and the segmental members lateral movement of car sections, a king bolt to Wlach the sills are attached by means o l the lugs and se mental portions, and means operativel y associated with said ltingbolt for pern'iiftting the car sections to adjust mselves to humps in the rails.

4 it oint for an articulation. in a car str t-ure composed of a plurality of car sections, comp-rising sills on the car sections, lug members secured to the sills near adjacent ends thereof, lug-receiving members in which said lugs roll, saidlug-receiving membersbeing movable ina limited angular path about a longitudinal axis, a plate membersecured to the car truck beneath the articulation, for supporting the lug-receiving members, a king bolt about which the lug-receiving; members move and about Which the lug members are fitted, aid king bolt projecting above and below said articulation and having; projections at each end, a spacing member between the plate member and the lowermost projection on the king bolt, and means for yioldingly urging the king bolt downwardly.

A joint for an. articulation in a car structure composed ot a plurality of car sections, comprising sills on the car sections, lug members secured to the sills near adjacent ends thereof, lu ;-receiving members in which said lugs roll, said lug-receiving members being movable in a lin'lited angular path about a longitudinal axis, a plate member secured to the car truck beneath the articulation, for supporting the lug-receiving menr hers, a king bolt about which the lug-receiving members move and about which the lug members are fitted, said king bolt projecting above and below said articulation and having projections at each end, a spacing member between the plate member and the lowermost projection on the king bolt, and a spring mounted between said projection and said spacing member for yieldingly urging the king bolt downwardly.

(3. In an articulated car, a truck located at the point of articulation, a cup-shaped eating fixed to the triiclnsegmental blocks mounted in the bearing, and a projection on each section of the car, each projection resting on one of said segmental blocks.

7. In an articulated car, a truck located at the point of articulation, a cup-shaped hearing fixed to the truck, segmental blocks mounted in the bearing, a cavity in the top sn race of each of said block and a projection on each section resting in the cavity on one of said segmental blocks. r,

8. ln a joint for articulated cars and in combination with adjacent car ends, a truck for supporting the same, longitudinally spaced elements carried by the truck and rotatable with ieiation to the truck about a common vertical pivot and transversely-extending elements extending down from the car ends and engaging the first-named elements, the engagement between the first and secondmalned elements permitting the adja cent ends of the car sections to rise, and fall to accoi'mnodate for breaks in the grade.
